Neither option is "good" or "bad".  It's a tradeoff between performance
(binary only driver) and reliability/debuggability/freedom (open source

It's almost certain that you'll get higher frame rates with the closed
source driver, as the vendor knows all the secret details of the

$ glxinfo | grep direct

If you see:

direct rendering: Yes

then HW acceleration is working.
